PORTLAND, Ore. (AP) - Police released the identity Saturday of an 18-year-old student who was tackled after reportedly bringing a gun into classroom at an Oregon high school.

Angel Granados Diaz had been booked into the Multnomah County Detention Center on suspicion of possessing a firearm in a public building, attempting to shoot a gun at a school and reckless endangerment, the Portland Police Bureau said.

He is a student at Parkrose High School, where he brought the shotgun Friday, authorities said. Witnesses told The Oregonian/OregonLive that he appeared distraught when he appeared at the door to their government class and pulled the weapon from beneath a long black trench coat, and that a football and track coach who also works security at the school, Keanon Lowe, tackled him before anyone got hurt. Lowe is a former football standout at the University of Oregon.
